Problems solved by technology

However, in the field device disclosed in Patent Document 2, since functions are switched in the order in which a plurality of switches are pressed, the user cannot intuitively understand the operation, and there is still a problem that the limitation of screen transition is still large.
[0006] In addition, a method of using a touch panel as a display and input device can also be considered, but there is a problem that the product cost becomes high.
[0007] In addition, the above-mentioned problems are not limited to field devices, and may also occur in other electronic devices equipped with display and input devices.

no. 1 Embodiment

[0048] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a front view of the display and input device of the first embodiment of the present invention, figure 2 Yes figure 1I-I line sectional view. The display and input device 1 includes: a printed substrate 2 as a base; a display unit 3 such as a liquid crystal panel mounted on the printed substrate 2; Magnetic sensors 4a, 4b, 4c, 4d such as magnetic sensors (Hall elements) for detecting approaching objects; and a glass plate 5 for protection of the display and input device 1 and shielding from outside air.

[0049] image 3 It is a block diagram illustrating the electrical connection of the display and input device 1 of this embodiment. The control unit 6 is composed of a display and input control unit 60 and an overall control unit 61. The display and input control unit 60 controls the display unit 3 and receives the detection results of the magnetic se...

no. 2 Embodiment

[0080] In the first embodiment, an example of using a magnetic sensor as a sensor was described, but a photoelectric sensor may also be used as a sensor. Figure 10 It is the front view of the display and input device of the second embodiment of the present invention, Figure 11 Yes Figure 10 The I-I line sectional view, for the figure 1 , figure 2 Identical structures are assigned the same reference symbols.

[0081] The display and input device 1a of this embodiment includes: a printed circuit board 2, a display unit 3, photosensors 8a, 8b, 8c, 8d near the four corners of the display area of ​​the display unit 3 mounted on the printed circuit board 2, a glass plate 5, as well as image 3 The control section 6 is shown. Similar to the first embodiment, 40a, 40b, 40c, and 40d indicate detection areas of the photoelectric sensors 8a, 8b, 8c, and 8d.

[0082] Figure 12 It is a figure explaining the operation|movement of the photoelectric sensor 8a. like Figure 12 A...

no. 3 Embodiment

[0089] In the first and second embodiments, the detection areas 40a, 40b, 40c, and 40d of the sensors overlap the four corners of the display area of ​​the display unit 3, but they may be located outside the display area. Figure 13 It is the front view of the display and input device of the 3rd embodiment of the present invention, Figure 14 Yes Figure 13 The I-I line sectional view, for the figure 1 , figure 2 , Figure 10 , Figure 11 Identical structures are assigned the same reference symbols.

[0090] The display and input device 1b of this embodiment includes: a printed circuit board 2, a display portion 3, magnetic sensors 10a, 10b, 10c, 10d made of magnetic sensors (Hall elements), a glass plate 5, and image 3 The control section 6 is shown. As described above, the detection areas 40 a , 40 b , 40 c , and 40 d of the magnetic sensors 10 a , 10 b , 10 c , and 10 d do not overlap the four corners of the display area of ​​the display unit 3 . That is, the dete...

Abstract

To provide an interface easy to use for a user. The invention provides a display and input device (1) provided with: a display unit (3) for displaying a screen for presenting information; a pluralityof sensors (4a-4d) that are disposed in the vicinity of the peripheral edge of the display region of the display unit (3) and that detect approaching objects in a non-contact manner; and a control unit that causes a screen to be displayed on the display unit (3) and causes marks (30a-30d) indicating the functions of the buttons assigned to the sensors (4a-4d) to be displayed on the peripheral edgeof each display region in the vicinity of the plurality of sensors (4a-4d). When one of the plurality of sensors (4a-4d) detects the presence of an approaching object, the control unit determines that the button assigned to the sensor that detected the presence of the object has been operated, and determines a process to be executed on the basis of the button.

Description

technical field [0001] The invention relates to a display and input device with display function and input function. Background technique [0002] For example from Figure 21 The perspective view of (a) and Figure 21 It can be seen from the front view of (b) that the field device with an explosion-proof structure having a screen display function has a front surface cover 102 embedded with a light-transmitting material 101 such as glass on the front surface of the display 100, and the display 100 will not be exposed to the outside air. middle. Therefore, in a conventional field device, the button 103 provided together with the display 100 is used as a switch using a photoelectric sensor, an infrared sensor, or the like (see Patent Document 1). [0003] In products such as field devices, the number of buttons that can be mounted is limited, and the names of the buttons are printed near the buttons. In existing field devices, it is difficult to realize multiple functions wit...
